Buffalo, in the county of Erie and State of? New York," have, invented a new and. .1139;- i ful Improvement in LabelingMachines,of

This invention relates to a lab. l ng vma-i I chine which ismoreparticularly designed .forapplyinglabels .to two part cigarettei boxes. betel-e the same ai'efilled'withgoodsn In boxe'sof this character the label is'usually appliedpartly .to both sections of the box;

across thetjointbetwe'en the same on one side thereof, so as to forms. hinge-connec-; tion between-these parts, while another part ofthe label is left free in the iorm of a flap .to'i 'permit'. of securingthe. same to the box parts across the jointv on the opposite side-of; v 0.

the samegafter the box has been filledwith goods. w

i It is the object oi. this invention to, pro- 'vide .a machine whereby labels may be at:

fixed in this manner to the parts'of cigarette or similar boxes expeditiously, a'ccu rately and economically;

.In the accompanylng drawings consist-1 ingof 7 sheets: Figure 1 is a side 6161 31131011 1 of my improved labeling'machine. Fig. 2

I Although my lmproved labeling machine may be used for applying labels towarious articles, it is more particularlyv designed for applying labels to two-part cigarette boxes preparatory to'filling the same, so that one part of each label is attached to the two partsof a box on one side of the same and across the adjacent part of the joint therebetween, and forms a hinged connection btween the same'while another part. of th' label is free and adapted to be adhesively at tached tothe parts of the box on the 0. csite side thereofand across the adj acent'part of the joint after the box has'been filled .With cigarettes, and thus seal the'same.

'This box vis preferably .of rectangular form, asshownin Figs. 2, 6, 7 and 11, and

comprises a'lower body 1 provided at its upper edge with a collar or neck 2, and-an upper part orcover 3 which fits .with its flange 4 over said collar. The label 5 is preferably-as wide as'tlilehgth of the box. and of such length that when it is wrappedtransversely around the two parts of the box the opposite ends thereof will overlap on one of the flat sides of the box, preferably the bott0m,and completely encompass'the same. In the operation of the machine, this label is pasted or adhesively attached with its central or' intermediate part to the top of the cover and with one end to the rear sides of the cover and body and partly on the bottom of the body, while the opposite end of the label is free and is ada ted to be subsequently attachedto the ront sides of the body .and cover and to the remaining part of the bottom of the body of the box.

' In its general organization, my improved box-labeling machine comprises an upper horizontal supply magazine adapted. to contain a horizontal stack or pile of unlabeled boxes, .a lower horizontal receiving magazine adapted to receive the boxes after the labels have been applied to the same, means The supply magazine which is adapted td" contain the supply of unlabeled'boxes, the bodies and covers of which have been previously assembled, preferably comprises a horizontal bottom 6 and two longitudinal side walls 7, 7. The boxes are stacked in this magazine horizontally with the rear edges of the bodies and covers resting on the bottom and the side edges thereof engaging with the side walls of the magazine and the bottoms of the boxes facing forwardly. At its front end, the supply magazine is closed by a transverse front wall -or abutment '8 toward which the pile of boxes in the magazine is constantly moved by means of a follower mechanism which, as shown in Figs. 1, 2, 6 and 17, preferably consist of a follower or plate 9 arranged in the magazine and engaging with the rearmost box therein and provided on laterally opposite edges with arms 10 which overhang the side walls of the supply magazine, a pair of flexible draft members or cords 11 each of which is connected at its opposite ends with one arm 10 of the follower and the rear part of one of the side walls of the magazine while its intermediate part passes around a pulleyor sheave 12 arranged on the front part of the adjacent side wall of the magazine, and another sheave 13 arranged on the rear part of the same wall, so as to form a forwardly? extending upper loop or bight in this draft cord and a downwardly projecting lower loop or bight in the same, a floating pulley or sheave 14 mounted on the rear lbop or thedraft end andaweight 15 connected with the floating sheave. As the boxes are fed successively from the front ends of the pile in the supply magazine, the pull of the weights 15 upon the follower 9 through the medium of the draft cords, causes the 'pile in the supply magazine to be advanced in the same measure as the boxes are fed off,

'1 and thereby bring the boxes successively to I the front endof the ile.

At its front end ad acent to its front wall, the bottom of the supply magazine is provided with an outlet opening or passage 16 through which the boxes are successively fed downwardly from the front end of the pile in the supply magazine. This feeding of the unlabeled boxes from this supply magazine may be effected by various means but preferably by the mechanism shown in the drawings which is best shown in Figs.

1, 2, 3, 6, 7 and 11 and which comprises a vertically movable feeding plunger 17 having its path of movement arranged in line with the outlet of the supply magazine and the gforemost box therein, vertical side the movement thereof, a vertically swinging rock lever or arm 19 arranged above the supply magazine and pivoted at its outer end on a bracket or standard 20 rising from the mainframe 21 or stationary part of the machine while its inner end is connected by an upright link 22 to the upper end of the plunger, a main driving shaft 23 journaled horizontally and transversely in the lower front part of the machine, a disk 24: secured to the driving shaft and provided with a cam 25'and a vertical cam rod .26 connected at its upper end with the plunger arm and provided at its lower end with a pin or roller 27 engaging with the plunger cam. The driving 'shaft makes one complete rotation in the direction of the arrow, shown in Figs. 1, 6 and 7, during each cycle of operations of the machine and may be op.- erated in any suitable way, for instance, by means of a driving pulley 28 adapted to be connected with the'driving shaft by means of a clutch 29, and to receive a driving belt. As' the' driving. shaft rotates, the plunger cam causes the feeding plunger 17 to be reciprocated vertically through the medium of the intermediate connecting mechanism. During each downward'stroke of'the plunger the same engages with the upper or front edge of the foremost box in the supply magazine and pushes the same downwardly throu-ghthe-' outletopening thereof. During the subsequent upward movementof the plungerthe same continues its movement in this direction until its lower. edgeis abgve the upper side of the stack of boxes in they supply magazine and when theplunger reaches this position, it clearsthe front of the stack of boxes in the magazine, and the stack is moved forwardly by the action .of the fol-1 lower mechanism, so that the next box at the front of the pile in the supply magazine is brought against the front of this magazine and over the outlet thereof, so that it is in position to be fed downwardly and discharged from the magazine by the subsequent downward movement of the feeding plunger. The widthof the magazine and the distance between the side guides 18 of the plunger'is such that the ends of the box engage'the same with sufficient friction to prevent .displacement of the boxes excepting under the action of the follower mechanism and. the

feeding plunger. Preparatory to feeding or discharging each box downwardly from pile-supporting table 30, the top of this pile being in line or substantially so with the position where the boxes first engage their undersides with the labels. These labels are fed successively rearwardly from the top of the pile to the position where they are assembled with successive boxes, and the pile supporting table isgradually and automatically elevated as the labels are fed off from the top of the pile, so' as to maintain the latter in the proper position relatively to the feeding-off mechanism. During its vertical movementthe label-supporting table is slidingly supported by means of an upright slide 31'connectedat its upper end with the rear end of the label-table and guided in ways 32 on theadjacent part of themain frame, as shown in Figs. 6, 3, 7

and 13.. The upward movement of the label-supporting table is effected by means of a lifting rod 33' extending downwardly fromthe center thereof, a flexible lifting member or cord 34 which is doubled to form a loo-p or bight which passes over a roller 35 arranged on an adjacent stationary part of the frame, and which is secured with one of its ends to the lower end of the lifting rod 33 while its other end carries a weight 36,- as shown in Figs. 6 and 7. The downward pull of. the weight 36 on the cord 34 pro: duces a constant upward pressure on the label supporting table and causes the pile thereon to be raised as the labels, are fed off successively from the top thereof. The pile of labels is guided on its laterally opposite sides, so as to prevent sidewise" displacement thereofby means of two upright guide walls on plates 37 engaging with laterally opposite sides of the pile of labels and secured or mounted on the adjacent stationary part of j the machine. Below the top of the p le, the

same is prevented from being moved or displaced rearwardly by means of a stationary rear wall 38 .arranged vertlcallym rear of the pile and engaged by the rear side-of the pile of labels, as shown in'Figs. 6, and 7.

The upward movement of the/pile of labels.-

is arrested by an abutmentor stop device which-is preferably so constructed as ,to

yieldingly. resist the upward movement of.

the pile and produce a slight tension upon the front edge of the uppermostilabel, pres paratory to feeding the same off from thepile. This yieldingtension or friction device preferablyconsists of a vertically movable tension or friction .pin 39 which is guided at its lower end in an opening formed in a stationary plate 40 extending horizontally across the top of the pile at the front "end thereof, while its upper end is guided in a socket 41 secured to a bracket 42 rising from the supporting plate. The tension pin 39 is preferably held yieldingly in its depressed position by means of a'coil spring 43 surrounding this pin andbearing at its upper end against the socket while its lower end bears against a collar 44 secured to this pin above the supporting plate. This collar also operates as a stop which, upon striking the upper side of the plate 4:0, serves to k limit the downward movement of a .tension ipin, and thereby prevent the parts from becoming displaced when no' labels are on the pile supporting table for engagement with this pin.

Means are provided for separatingmthe uppermost label from the top of the pile preparatory to feeding the same off from the pile and into position for. assembling the same with a box which is fed off from the supply magazine. nism for this'purpose shown in the drawings is constructed as follows: 45- repre- The preferred mechasents a separator,'wiper or 'separatingfinger which is preferably constructed of rubber or similar flexible material and which has a vertically vibrating or oscillating movement top of the uppermost label at the rear endthereof from the positionshown'in Fig. 6

to the position shown in Fig. 9, whereby the rear end of the uppermost label is pushed forwardly and an upward buckle produced in the same, as shown'in Fig- 9, thereby separating or loosening this label. During this movement of the separator, forward displacement of its front endis prevented by reason of the pressure upon the same of the spring pin 39 and also by engagement of the front edge of this label with a stop or flange 46 which projects downwardly from the supporting plate 40 along the upper part of the front side of the pile of labels, as-shown in Figs. 6, 7, 8, 9 and 10. The separator is secured tolthe outer section 47 of a jointed rock arm which ispivotally connected with an inner section 48 which latter in turn is secured to arock shaft 49 extending transversely over the'pile of'labels and journaled .in bearings on the adjacent stationary part of the frame. On opposite sides of the pivotal connection betweenethe two-sections of the rock arm,-the

55-edge of the ,label forwardly from undersection but permit the outer section to change its position sufficiently withreference to the, inner section to enable the separator to adapt itself properly to the upper.

so as to clear this label, whereby the latter is again permitted to straighten out, as

,shown in Fig. 10. The rock shaft 49 is.

preferably operated for producin this oscillating movement of the separating finger by the means shown in the drawings which consists of a gear inion 51 secured to one end of the rock s aft 49, a reciprocating gearrack 52 meshing with the pinion, a rock lever 53 pivoted on a stationary part 2 of the machine and having one arm connectedwith the lower end of the gear rack, as shown for instance in Figs. 4,6, 7 and 13,

a .a spring 54 connecting'said gear rack' with I ,a stationary part of the machine and operating to raise the same,.and a cam 55 formed on the face of the disk 24 and engaging wit'lta roller 56 'on the other arm of the rock lever 53 and operating to turn the latter in a the direction for lowering the gear rack.

, 3o After the separator has pushed the rear 0 venting rengagement of the rear part of the label with the pile and lifting the same, preferably comprise avertically-swinging lifter or lifting finger. 57 which pro ects with its free front end over the top of the pile at the rear end thereof while its rear endissecured to a horizontal rock shaft 58 arranged transversely in rear of the pile of labelsand journalcd in bearings on the adjacent stationary part of the machine.

lVhile the separating finger is sweepin forwardly over the uppermost label, the llfting finger raised out of engagement from the top ofthe uppermost label, so as to permit ..the separatingfingcr to withdraw the rear neath the lifting finger, as shown in Fig. 9,

and after such withdrawal of the label, the

lifting finger-Wis depressed upon the next lowermost label. .of the pile, so that during so thesubsequent backward movement of the separating finger the rear portion of the label upon again straightening out, will pass over the topof the lifting finger, as shown in Fig. 10. After the sheet has thus straightened out, the separating finger continues its backward and upward movement,

so as to clear the space between the same and the lifting finger and permit the feeding off mechanism to ap roach the rear edge of the label, and the hfting-finger is also raised so as to lift the rear edge of the label into position to permit the feeding oif mechanism to grip the same, as shown in Fig. 7. To permit the rear end of the label to again straighten out after being buckled and to pass over the top of the liftin finger, the front or operative end of the atter is tapered or constructed in' the form of a knife edge, as shown in Figs. 6 and 10, thereby avoiding the 1 sentation of a shoulder or obstructing face a ainst which the" rear edge of the labelmig t engage or become caught and thus prevent" such f straightening out. The separator or separating finger is provided centrally with a notch or recess 59 which is in line with the lifting finger and permits the separator to swing freely over the pile of labels and the lifting finger without interfering with the latter. The rocking movement of the lifting finger and its shaft is produced preferably by the means which are best shown in Figs. 1, 2, 3, 11 and 12 and which comprise a rock arm 60 secured to one end of the lifting rock shaft, an upright connecting rod 61 connectedat its upper end with the r0 k, arm 60, a cam 62 arranged "on the main dr v4 ing shaft and engaging with a roller 63 oh the lower part of the rod 61- for raising the lifting finger, and a spring 64 connected with the rod 61 and an adjacent stationary part of the frame and operating to depress the lifting finger.

The preferred means for carrying off the labels successively from the top of the pile to the position where the. same are assembled with the boxes is best shown in Figs. 1, 5, 6, 7, S, 11, 12 and 16,- ia-nd are constructed as follows: 65 represents a horizontally and lengthwise reciprocating slidecor car: riage which is arranged below the upper or supply magazine and guided at its opposite longitudinal edges in ways 66 on the adjacent stationarypart of the-machine. At its front end the slide 65 is fprovided with a 115 gripper composed of a lower jaw 67 rigidly I mounted on the slide and an upper jaw 6 pivoted on this slide and movable vertically toward and from the lowe'rjaw for gripping the rear edge of the uppermost label between the same or to release this label. The lower jaw is bifurcated so that in its foremost position the same can pass along opposite sidesof. the lifting finger and underneath the .elevated rear edge of the uppermost label.- The upper' jaw 'is yieldingly held in. its closed position by a spring 69 which is preferably constructed in the form of a 001i surrounding the=pivot of the upper aw and-bears with one end against the upi30 per-sideof the upper jaw while-its other end bears against the adjacent part of the gripper slide 65. ,The upper gripper jaw may beheld inits elevated or open position by means of a trigger, pawl or latch which is pivoted to swing vertically on the gripper carrier and has a front arm 70 adaptedto engage'with the heel 71 of the upper gripper jaw and a rear arm 72, whereby the trig- 1o ger or latch is operated for releasing its front arm from the upper. gripperjaw. A spring-73 preferably interposed between the upper side of a cross piece onthefgripper carrier and the underside of the front arm of the trigger or latch operates constantly to i turn the trigger in the direction for lifting the front arm thereof when free and engage I the same with the heel of the upper gripper jaw and hold the latter in its elevated posi- 29 tion, 74 represents a vertically movableshifting pin guided in an opening formed in the stationary part of the machine in such position that when the gripper slide and as sociated parts are in their rearmost position,

' the upper gripper jaw will be arranged over the shlftmg' pm, as shown in Fig. 6, and

I when the gripper slide and associated partare in their-foremost position the rear. arm of the trigger will be over the shifting pin, as shown'm Fig. 7 This shifting pin'is raised twice during each. cycle of operations 'of the machine, once whenthe gripper slide .is at the front end of its stroke and again when-said slide is at the rear end of its 3 5 StI'Oke, this movement being preferably effected by means of a horizontal rock shaft shifting pin at the front and rear ends of the stroke of the gripper carrying slide, and a spring 79 which operates to turn said rock arms and shaft in the direction for permitting-the shifting pin to descend when the low faces of the cam 78 are presented. to the roller of the rock arm 77 and which is: preferably connected at its opposite ends with the rock arm 77 and the main vframe of the machine, as shown in Fig. 1. During'the forward movement of the gripper carrier, the upper gripper jlpw is elevated and held in this positionbv t geiengagin with the heel thereof, as shown 66 m Fig. t is having been efiected bythe nosaeao shaft and provided with two high faces on areturned in thedirection for raising the 8 front arm of the trigmovement of the trigger into engagement with the heel of the upper gripper aw by means of the spring 73. portion of the forward movement ofthe gripper slide and v the open gripper,-, the

mechanism, causing the trigger to be turned inthe direction for disengaging its front arm from the heel of the upper gripper jaw, thereby permitting the spring 69v to move the upper gripper jaw toward the lower edge of the uppermost label between the same, as shown in Fig. 7. The gripper, slide now moves rearwardly and withdraws the pile, and moves the same across the path of the next following box which is fed downwardly from the supply magazine. When the gripper slide reaches the rear end of its stroke, the shifting pih'7e is again raised by its operatingmech'anismfor releasing the grip of the upper jaw upon the,

the front arm of the trigger is lifted by the spring 7 3into engagement with the heel of the upper gripper jaw, as shown inFig; 6, thereby holding the gripper open preparatory to eflectingthe nextfor'ward stroke of the same with the gripper slide. The recipbe effected by various means but preferably lower part of the main frame while its up-f per end is connected by a link 80 witha downwardly projecting lug 81 on; the rear shifting rod 82 connected at its rear end wlth the rock lever 790, and a cam 83 sewith a roller 84 on the shifting rod, as shown in Figs. 1, 5, 6, 7 and 13. \In order to enable the jaws "of the grlpper to obtain edge of the label, the faces of these jaws are preferably provided with a cooperating rib 85 and groove 86,.the rib being prefera y formed on the lower jaw and the groove the upper jaw,"= as shown-be'st-in vFig. 1 whereby a slight kink is produced in the rgar edge of the label when the gripper jaws close upon the same,thereby insuring a posi of the labels from the pile by the pressure of the spring pin- 89 against the upper side of upward movement of the I shifting .pin in" this position of the gripper slide and the During the last lower jaw passes underneath the rear edge ,of the uppermost; label" which'. has been gripper jaw and clamp or grasp the rear rear edge of the label, and while thus raised,

At the back of the face of the labels in the correct position forassembling the same properly with the boxes. In order to prevent the rear edge of the label from getting over the upper side of the gage face, the same is provided with a forwardly-projecting retaining pin or lug 88- between which and the gripper face of the lower jaw the rear edge of the label is received preparatory to being gripped by the upper jaw. I

As the labels are carried from the pile supporting table rearwardly into a position across the path of the boxespreparatory to being assembled therewith, these labels are held against lateral displacement by two longitudinal gages or guide bars 89 arranged lengthwise on opposite sides of the path of the labels and adapted to be engaged with the longitudinal edges thereof, thereby insuring'proper presentation of the labels to the boxes for producing neat work an'daccurate assembling of the same. These side bars or gages are capable of lateral adjustment for adapting them accurately to the width of the labels, this adjustment being preferably effected by means of trans, verse screws 90 secured at their inner ends to the guide or gage bars while their outer -ends slide in lugs 91 on the main frame,

screw nuts 92 applied to the outer ends of these screws and bearing againstthe outer ends of said lugs, and a spring 93 surrounding each of the screws and bearing at its opposite ends. against the outer side of one of the side guide bars'and the support-ing lug of the respective adjusting screw. Upon tightening the screw nuts 92. the guide bars are moved outwardly and the springs are compressed, while upon loosening these screw nuts said guide bars are moved inwardly by the springs 93.

In order to permit of accurately setting 1 the gripper slide so that its stroke will be suited to the length of the label which is being applied to the boxes, means are provided for adjusting this stroke. This is preferably effected by making the shifting rod' 82' adjustable lengthwise of the rock arm or lever 790 by providing -the latter with a longitudinal slot 94: which receives an adjustable pivot pin or screw 95 on the rear end of the shifting rod 8 2. In making the machine ready, the shifting rod 82 is disconnected or loosened on the rock arm- 790 and the gripper slide is'moved backwardly against a set screw 96 mounted on an adjacent stationarv part of the machine. This screw has previously been set in ac cordance with the predetermined point at which the grippers shall come to rest with the label; The shifting rodj82 is then" connected at the proper point with the rock arm 790 and thereafter the labels will always be carried by'the grippers to the-same position for assembling with the boxes. .1

As each, label is fed off from the top "of the pile, the intermediate or central part and the front end of the same are coated with paste, glue or other adhesive material" for securing the central part of the'label to the rear side of the ,box while the same is in its assembling position; and securing the front end of the label to the underside of the body and the lower'part of the front side, while the rear end of the label remains uncoated and is adapted tobe secured t6 the top of the box and upper part of the front side after the goods have been placed inthe boxes. The-preferred mechanism for thus applying the adhesive successively to the labels which is best shown in Figs. 1,

2, 3, 6 and 7 of the drawingsis constructed as follows: 97 represents a pot. arranged zontal shaft 99 journaled transversely .in

bearings on the glue pot. On the front or lifting side of the paste supplying roller the same is engaged by a regulating roller 100 which is'adapted to remove the excess of paste from the supplyroller and thus regulate the amount of glue orpaste which is delivered to thelabels. The shaft of this regulating roller is journaled in bearings 101 which are movable in stationary guides 102 toward the supply roller and are engaged on the front sides by means of adjusting screws 103 mounted on adjacentstm tionary parts carried by the glue pot. By tightening or loosening these screws. the pressure of the regulating roller against the supply roller may be Varied to suit the amount of paste or glue which the supply roller is to lift from the glue pot. On its upper rear side the supply roller is engaged by a transfer roller 104 which is mounted on the horizontal transverse shaft.105"jour naled in bearings 106 which are movable horizontally in longitudinal guides 107 formed on side pleces cf the glue pot. anc are engaged by means. of screws 10S mounted on said side-pieces forpressing the transfer roller against-thc= supplv roller.- The supply roller; regulating roller and, transfer roller arecaused toitu rn in unison in the direction indicatedby thc arrows-in Figs. 1 and 6 by means'i-ofa gear wheel 109 secured to one end of the shaft of the supply roller and meshing with a pinion 111), and a gear wheel 111 on the corresponding ends of the shafts of the regulating roller and the transfer roller. Motion is derived from the main driving shaft for turning the above described rollers of the paste supplying mechanism by means of a 115 represents a glue or paste delivering I roller which vibrates vertically and engages alternately with the underside of the glue transfer roller'and the central part of the a top of the pile labels. This rolleris carried on the rearends of a pair of vertically swinging rock arms :116 which are] secured at their front ends to a horizontal rock shaft- 117 journaledtransversely on a stationary part of the machine adjacent to the lower front end of the glue pot. The rock shaft is operated for'efiecting the described vibrat ing movement; of the delivery roller by means of .a rock arm 118 arranged on one end ofthe delivery rock shaft, a rock lever 119 on the main frame having its front arm connected by an upright link orrod'120 with the arm 118 on the delivery rock shaft, a spring 121 connecting the rear arm of the rock lever 119 with the mainframe and operating to turn the same and the parts connected therewith in the direction for moving the gluedelivery roller from the avitlithe supply roller. so

While the delivery roller is in its elevated position and in contactrwith the underside of the transfer roller, as shown in Figs. 1 and 6, it isrotated' by contact with the transfer roller and receives the glue which the latter has received by contact After the delivery roller .has been thus coated with glue, the same is lowered upon the central part of the uppermost label of the pile, this occurring immediately after the rear part of the uppermost label has been doubled and again straightenedout, so that this label upon being subsequently Withdrawn rearwardly from the top of the pile by the gripper mechanism will be drawn with its central and front part underneath the glue delivery roller, as shown in Fig, 8 and receive a coating of glue or paste therefrom. After I the up er label has'been'thus drawn rear- I 'wardly in contact with the delivery roller to coat the central and front part of the label. this delivery roller is again elevated into contact with the transfer roller for receiving a supply of glue for coating the next ,following label withdrawn from the pile. versely across the path of the descending While .the label is arranged trans box with which the same is tofbe assembled,

this label is supported on its underside by; means of avertically movable platen 124'}; whichis arranged vertically in line with the. path of movement-trf-the box feeding plunger. The movement of this platen is rest underneath the fed-0H label and while the box is being fed downwardly against the label and when the under or-advancing side of the box has engaged the label,"the platen begins its downward movement and moves in this directionin unison with box feeding plunger until the box and the label associated therewith have reached the position where the assembled box and label are discharged from a position between the feedmagazine. being thus carried downwardly, they are so timed that it remains mdmentarily at ing plunger and platen to the reeciving V While the box and l'abelare.

firmly gripped between-the feeding plungeran'd platen and thatpart= of the label engaging with the outer sides of the cover and body are firmly pressed together and [caused to be united. The platen is of the same length as the width of the label in order to apply pressure against the full width of the same. The face of this platen is provided with a facing or cushion 125 of rubber or similar flexible-material, whereby a yielding pressure is produced ont-he lower side of the box, whereby the box and label may be gripped between the feeding plunger and platen without necessitating absolute accuracy in the relative, position between the feeding plunger and platen. ,jhe yielding face of the platen also permits. the same to adapt itself to any irregularities or unevenness on the lower side of the box and causes the-respective partof the label to be reliably and smoothly attfached thereto throughout its entire sur ace. downwardly between the feeding plunger and platen, the front end of the label is folded upwardly and adhesively attached to the vertical bottom or front side of the box, and the intermediate part and rear end of the label are folded upwardly against the vertical rear side of the box, the paste coated intermediate portion being adhesively secured to this side of the box while the uncoatedjupper rear end of the labelprojects upwardly above the upper side of the box in the form of a loose flap.

mediate and rear'e-nd of the label relatively to the box and the pressing of the front end and intermediate parts against the flat frcntand rear sides of the box is preferably As. the box andlabel are carried I y This folding of the rear end and the inter- -the position where the box and label are -35 the label and the intermediate part may be :60 machine toward and from the rear pre'ss-' effected by means of front and rear folding and pressing members arranged in front and rear of the path'of the la'bel, box, feeding plunger and platen immediately below assembled and separated from each other by an intervening passage or throat through wv-hich the platen, feeding plunger, label and box are moved downwardly. These? folding and pressing members preferablyfi consist of two'brushes the bristles 126 of which face the front and rear sides of said throat while their stocks 127 erg-secured in? an opening formed in the maiiig frame or.

stationary part of the machine immediately.

in rear of the .top of the pile of labels. As the box and label are carried downwardly between the feeding plunger and platen,; those parts of the label in front and in rear:

2 of the'box are folded or turned upwardly into a vertical position and pressed against;

the front and rear sides of the box by the wiping action of the bristles of the brushes. Inasmuch as these brushes yield, theyreadily adapt themselves to any unevenness or irregularities on the front and rear surfaces of the 'box and thereby cause the front and rear pasted parts of the label to be uniformly and smoothly attached to the box over the entire surface covered by the pasted. parts of'the label. After the box with the label folded upon and attached thereto passes downwardly beyond the folding and pressing. brushes, the front end of subjected to additional pressure if this is found necessary, this being effected by a secondary pressing device which preferably comprises front and rear pressingplates ,40 128, 129, which are arranged in front and in rear of the path of the box and label below the upper or primary folding and pressing device, and which are adapted to engage with the front and rear sides .of the label and press the same firmly against the corresponding sides of the box during the downward movement of same between the secondary pressing plates. The latter prefv erably operate yieldingly upon the label of .50 the box, so as to allow for any variations in the thickness of the box and label and enable the secondary pressing device to adapt itself to the box and label for properly pressing the same.- For this purpose the rear pressing plate is preferably mounted rigidly on an adjacent stationary cross bar 130 of the,frame while the fronti'pre'ssing" late is mounted on. a cross bar 131 which is capable of longitudinalmovement .inithe ing plate, the same being guided by means of screws 132 arranged on the frame and: passing through glongitudinal slots 133 in the front cross bar and being yieldingly held in its rearmost position by means of springs", 134 interposedbetween the .front side of the front bar and adjacent stationary part of the machine, asshown in'Figs. 6,

7 and 8. After the assembled box and label while moving downwardly with and between the feeding plunger'and platen have passed below the secondary pressing de-- vice, the platen completes its downward movement and remains at rest while the feeding plunger immediately ascends into its highest osit-ion preparatory .to feeding downward he next box from the supply magazine. The platen. remains in this depressed position until the mechanism which removes the labeled box from the plat'en into the receiving magazine has completed its operation, and then the platen again rises into a position substantially in line with the upper side of the'p'rimary folding brushes and below the transverse path of the labels as the latter are moved from/the supply pile across the. downward path of the boxes The mechanism whereby the platen is moved in the mannerdescribed' 1 may be variously constructed but that-shown in the drawings is suitable for the purpose and comprises an upright narrow slide, 135' which has its lower part constructed "in the form of a rod which is guided in a way 136 on the main frame while its intermediate part is slotted and receives the main driving shaft so as tojbe guided thereon and has its upper end connected cent-rally with the underside of the platen, This platen supporting slide is reciprocated ver-- tically by means of a transverse "rock lever 137 pivotally connected at its inner end with the lower part of the platen slide while its outer end is pivoted on the main frame,

an upright shifting rod 138 connected at its lower end with theplaten operating lever, a cam 139 formed on the disk 24 and operating to depress 'the connecting rod and the platen through the medium of the slide 135 and lever 137, and a spring140 which operates toraise the platen and which is preferably connected at one end with the lever 137 and at its .opposite'end-with the main; frame, as shown in'Figs. .7 and 11.

The receiving magazine 'n'i which the labeled boxes aresta'eked is arranged liori "z'ontally in rear "of the space between the secondary pressingdevice and'the platen in 'thewl owermost position thereof and com prises a. horizontal longitudinal" bottom 141,

rising from opposite sides of theibo'tt'om a horizontal longitudinal top lft t connect ingjthe'side walls, 1 The upper-"'sidebf the bottom of the receiving magazine' is' hori is provided'at its front end with a longitudinal slot 145 through which the platen slide moves vertically and on transversely .142", two upright longitudinal side walls 143 n i ipreceding boxes are pushed opposite sides of this slot with notches or recesses 146 which are adapted to receive' the ends of the platen in the lowermost position thereof. i

The mechanism whereby the labeledboxes are successively removed from the platen and delivered into the receiving magazine is preferably constructed as follows: In front of the receiving magazine is arranged a horizontally and longitudinally movable 'packing plunger which comprises two longitudinal side pieces .147 guided 011 the opposite outer sides of the front part 141 of i the bottom of the receiving magazine, a cross piece or yoke 148 connecting the side pieces 147 below the bottom part of the receiving magazine, and two push fingers, wings or horns 149 projecting inwardly from the upper side of the side pieces and separated from each other by an intervening space which is vertically in line with the slide of the platen. During the downward movement of the labeled box together with the platen and feeding plunger and until '25 these parts reach their lowermost position,

the packing plunger is in its foremost position so that' its push fingers or wings are arranged in front of the labeled box when thesame reaches the end of its downward movement with the feeding plunger and platen. Upon reaching this position and after the feeding plunger has commenced its upward movement, the labeled box is engaged on its front side by the push fingers of the packing plunger which now moves rearwardly. The

extent of this movement of the packing plunger is such that it removes the labeled box from the upper side of the platen and pushes the same into the front orinlet end 4:0 .of the receiving magazine. After having delivered the labeled box in this manner into the receiving magazine, the packing plunger again movesforwardly into its foremost position and the platen is raised into its uppermost posit-ion, .preparatory to receiving the next following box and label. The mechanism whereby this reciprocating movement of the packing plunger is obtained preferably comprises an upright rock lever 150 pivoted at its lower end on the main frame and connected at its upper end by alink 151 with the yoke of the packingplunger, a shifting rod 152 connected at its rear end with the upright lever 150 and a cam'153 secured to'the main driving shaft and engaging with a roller 154 on the front part of the shifting rod. As the labeled boxes are delivered successively into the frontend of the receiving magazine, the rearward by successive steps as" the new incoming boxes are added to the front of the stack therein. As each labeled box is pushed rearward-1y into the receiving magazine the same is preventedfrom again springing forward as the packing plunger is withdrawn forwardly by. means of a detent device which is shown in Figs. 7, 14 and 15 and which preferably comprises two longitudinal springs 155 arranged lengthwise on opposite vertical sides .of the 1nlet at the front of the receiving magazine and each secured at its rear end to the adjacent side wall of the receiving magazine while its front end is provided on its inner side with a rearwardly facing shoulder 156 and a forwardly facing incline 157 arranged in front .of the shoulder. As a box is pushed rearwardly by the packing plunger, the vertical sides of the box by engaging the inclines on the detent springs deflect the latter and hold the same apart until the front side of the box passes'rearwardly beyond the shoulders of these detent springs when the latter owing to their resilience move their shoulders in front of the box and thereby prevent the same from moving forwardly during the subsequent forward movement-of the packing plunger.

The distance betweenthe bottom and top of the receiving magazine is greater than the height of the box but less than the added height of the box and the upwardly extending loose end or flap of the label thereon, and the undersideof the top of the receiving magazine at its front orinlet end is beveled downwardly, as shown at 158 in Fig. 7.. By means of this construction, the loose rear end or flap of the label upon pushing the box into the receiving magazine is gradually bent forwardly and downwardly over the upper side of the box, as shown in Figs. -6 and 7. To complete this forward bending of the loose end or flap of the box and cause the same to be creased at the upper rear corner of the box, a pressing device is provided whereby pressure is applied to the'opposite upper and lower sides of the boxes. This pressing device preferably con sists of a presser block 159 movable vertically through an opening formed in the bottom of the receiving magazine and provided on its upper side with an elastic facing 160, a vertically movable cross head or slide 161- upon which said presscr block rests loosely and which is guided upon upright rods 162 secured to the main frame, a pair of upright. toggle links 163 pivotally connected at their opposing ends while their. extremities are pivoted respectively to the underside of the cross head 161 and a stationary support-011 the lower part of the machine, and a connecting rod 164 connected at its rear end with the opposing ends of the toggle links while its froht end is connected with they rock lever 150. As the rock lever 150 oscillates and actuates the packing plunger, the toggle links are alternately folded and straightened and cause the presser block to rise and fall. In .the'loweri'nost position of the presser block, the upper side of its elastils:

facing isfiush 'withtheupper side of the bottom-of the' receiving magazine, as shown 1n Fig. 7;As the boxes" are pushed rearward in the receiving magazine by the packing plungerythe same are moved successively over the presser block and as the packing plunger moves forward the presser blockrises and lifts the boxes resting thereon, so that their upper sides and the for- O-wardly,overhanging label flaps thereof are pressed against the underside of the top of the receiving magazine, whereby these 121- beled' ends or flaps are creased at the upper rear box corner, thereby permitting of more convenient packing of these boxes for storage or transportation and also facilitating the pasting of these loose ends or flaps across the front sides of the covers and bodies and-the underside of the latter after the boxes have been filled with cigarettes or other goods; The presser block is equal in length to a plurality of the boxes, so that the same box and its label flap are subjected several times to the creasing operation of this presser block from the time that the box and its labels are first acted upon by the presser block to the time'that the boxes escape therefrom, thereby insuring reliable same is so constructed and mounted in. a ma-' chine that it can be quickly removed from the machine and restored in the same. This is preferably accomplished by constructing the bottom of the receiving magazine in two 4 sections 141, 142 which are detachably connected by means of bolts 165' or otherwise,

the front section 141 remaining permanently in the machine while the rear section 142 ispermanently connected with the side walls and top of the receiving magazine and is removable therewith from the machine. The removable parts of the receiving magazine are farther held in place while the machineis in operation by means of a bracket 166 projecting rearwardly from the main frame and connected with the rear part of the top of the receiving magazine by a screw 167, as shown in Figs. aiicl1, or

by any other suitable means.

To permit of removing the presser block from the 'machine with the receixing magazine but preventing the same from becoming -detached from this magazine when lifted from the cross head, retaining means are provided which preferably consist'of hooks 1 or' notched arms 168 projecting forwardly and rearwardly from the lower part, of the presser block and adapted to engage with cross rods or supports 169 mounted upon the adjacent part of the receivingmagazine.

jThese supporting rods are engaged by the tively to the receiving magazine, so that the same will not fall apart when clearing the magazine, thereby facilitating handling of the receiving magazine when the same becomes clogged and avoiding prolonged stoppage of the machine for the purpose of clearing this magazine.
